-Subject: [PATCH] shared/util.c: assert_cc() can only be used inside functions
-
-shared/macro.h has two versions of assert_cc, one that uses gcc
-_Static_assert(), which requires recent enough gcc versions, and one
-that uses a fake array to trigger a build error. The latter can only
-work inside functions, so assert_cc() should only be used inside
-functions.
-
-Fixes the following build failure when building kmod with old gcc
-versions such as gcc 4.3.x:
-
-shared/util.c:52: error: expected identifier or '(' before 'do'
-shared/util.c:52: error: expected identifier or '(' before 'while'
-
